A fingerprint sensor could be one of those cool features that
everyone talks about, but nobody ends up using in their
day-to-day lives because it’s too much of a hassle. I’ll be
honest, heading into the event, I was wondering if Apple’s
implementation of the sensor would be good enough to actually
make it useful. Not just for a demo to make people gasp and clap,
but could I use it every day.

The answer is unequivocally yes.

The whole front page of The Loop is chockablock with great iOS 7 links. I won’t bother duplicating them, just go to The Loop and load them into tabs from there.
